SPECIFICATION forming part of Letters Patent No. 603,411, dated May3,1898.

To all whom t may concern." Be it known that I, FRANCIS S. RUTscHMAN, acitizen of the United States, residing in the. city and county ofPhiladelphia, State of Pennsylvania, have invented a new andusefulImprovement in Apparatus for Plotting or Treating Soap or other PlasticMaterial, of which the following is a specification. My inventionconsists of an apparatus for plotting or otherwise treatingsoap or otherfor preventing the adhesion and backing up of` the material in thecylinders employed within the case of the same and clogging of theapparatus.

Figure 1 represents a partial horizontal section on line y y,'Fig. 1,and a partial plan View of a plotting apparatus embodying my invention.Fig. 2 represents a transverse section thereof on line x fr, Fig. 1.Fig. 3 represents a partial horizontal section and partial top view of adetached portion of the apparatus. Y

Similar letters of reference indicate corresponding parts in thefigures'.

I Referring to the drawings, A designates a case or chamber having jacketed coverings B for the sections thereof andcontaining the hollowdrums or cylinders C, whose journals D and D are hollow and mounted onthe case, so as to be in communication with the intecooling medium maybe admitted thereinto. l

Connected with the journals D', which con-V stitute the outlets of thecylinders, are shafts E, to which are keyed or-'otherwise secured thegear-Wheels F, whereby Yrotation may be ward each other. In saidjournalsD are discharge-ports G, which communicate with the box I-I, thesame inclosing the outlet portions of said journals D and is providedwith an opening or pipe D2 for the discharge of said medium.

On the peripheries of the cylinders C are spiral grooves J, the groovesof one cylinder being pitched in the direction in reverse of the other,it being seen that the cylinders are arranged parallel and have therises of the thread closely together, while the grooves of the threadsform the pitched passage K between the cylinders, which passage is incom- SerlalNo.638,343.

munication with the discharge-pipe L of the case.

M designates endless passages or recesses formed on the wall of thejoint between the two sections which constitute the case aside ofthecylinders C, each of said passages having between the sides of the samethe wall N and outside of the same the wall P, which walls constitute inthe present case portions of the upper side of the lower sections of thecase. Occupying said passages M are the traveling'disksA or rollers Q,it being noticed that one length of each set of rollers partly occupiesthe grooves J, on which may be termed the outer sides of the cylinders.The other portions of said lengths of rollers are covered by walls ofthe sections of the case, as seen at R, Fig. 2, the rollers of saidlengths thus acting as cut-offs on the inner sides of the case7 as willbe hereinafter more fully explained. The other lengths of the sets ofrollers are inclosed by the wallsof the sections of the caseand the wallN and portions P of said sections.

The casing is provided with the hopper S, whereby the material to beplotted or worked may be directed into the same.

It will be seen that when rotary motion is communicated to the cylindersand the case supplied with soap or other material in proper conditionthe latter is carried into the pitched passage K and forced by the same,as by the action of a screw, throughout the case into the pipe L, fromwhich it is discharged. Should particles of the material adhere to thecylinders, the disks Q in the grooves J act as Scrapers or wipersthereforand cut-offs bevtween the cylinders and case, so that thematerial is prevented from backing up on the cylinders, improperlyturning over the same, and clogging the case. As the cylinders rotate,owing to the groove J engaging with the disks, traveling motion isimparted to said disks. The latter are carried around continuously inthe passage M and return successively to the groovesV J, so .that thelatter will always be freely illed or occupied by the disks, while thetraveling is uninterrupted, it being noticed that the disks are guidedin the passages M and prevented from displacement and interference witheach other owing to the walls N and the adjacent portions of IOO thecase. As water is introduced into the jackets B and also into thecylinders C, the latter, and consequently the material, will be cooled,in which condition the matter is effectively worked and solidified andso discharged.

Of course the material may be in liquid condition in order to be workedor treated in the apparatus, and so I do not limit myself to the use ofthe apparatus to plastic material.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

l. An apparatus for thc purpose described consisting of a case andhollow cylinders therein, said cylinders having spiral grooves thereonand provided with hollow journals, said case having traveling wiping andcut-off devices which are adapted to successively enter said spiralgrooves and freely close the same.

2. An apparatus for the purpose described having cylinders and wipingand cut-off devices adapted to travel in spiral grooves in saidcylinders.

3. A case provided with endless passages and traveling wiping andeut-off devices occupying said passages, in combination with cylindershaving spirally* grooved peripheries, portion of said wiping and cut-olfdevices freely entering said grooves and another portion entering theportions of the passages between the cylinders and walls of the case.

4. A case having endless passages in the walls thereof, movable wipingand eut-off devices adapted to travel in said passages and cylindershaving peripheries with spiral grooves thereon, into which latter saiddevices successively enter to close the same at the adjacent part of thecase.
